【摘要】：在汽车制造业中,新车型更新和变革时刻在发生,甚至为了应对法规及国家的要求,厂区的重新规划、生产线的重新组合都有每年一小变,三年一大变的趋势。因此,我们如何在应对这些变化的同时依然可以保证汽车制造的平顺性和制造变革的稳定性,是现在非常重要的课题。正如一个全新车型的生命周期初期,其车身装配和工艺方式都发生了极大的变化。但是为了保障产能,生产节奏必须保证快速和稳定。问题也随之诞生,全新的产品,全新的工艺,一旦在汽车设计阶段和生产管理中出现疏忽,汽车产品缺陷的概率就会非常大。随之而来的是客户满意度的下降、制造返工率的提升。这样一来,无论对于制造成本还是市场地位都有不利的影响。所以,如何提高汽车有效生产的合格率非常的重要。本文的主要工作如下:第一,对汽车制造质量管理进行了研究,并着重研究了两个管理工具:质量功能展开法(QFD)和故障模式与影响分析法(FMEA)的理论方法和实际应用步骤。第二,开始自己的综合研究,起初在对于QFD的研究中,引入了问卷调查法、专家访谈、卡片风暴、KANO模型等途径来帮助分析客户的需求,在QFD输出质量功能后,针对FMEA引入了双格田字格的分析方法,形成了以QFD和FMEA两个管理工具为主,问卷调研,专家访谈,卡片风暴、KANO模型和双格田字格为辅助途径的基于客户驱动的集成化质量管理综合模型。第三,开始针对汽车制造中出现的问题进行改进措施。由于在Model-M的制造上使用了新的工艺方式,而这些工艺方式的更新带来极高的缺陷率。文中就以某汽车制造企业Model-M汽车制造为实际案例,通过第一批制造中大量的产品缺陷数据对制造的设计环节进行了深入分析。最后进行了集成化质量管理综合模型在Model-M汽车第二批制造中的改进应用实践,得出改进效果,从而验证了该集成化方法对帮助提升质量的有效性,从而提升了该企业质量管理水平。
[Abstract]:In the automobile manufacturing industry, the renewal and transformation of new models are taking place at all times. Even in order to meet the requirements of laws and regulations and the requirements of the country, the replanning of the factory premises and the recombination of the production lines have the trend of one small change every year, and one big change in three years. Therefore, how to cope with these changes while still ensuring the ride comfort of automobile manufacturing and the stability of manufacturing change is a very important issue. Just as in the early stages of the life cycle of a brand-new model, its body assembly and workmanship have changed dramatically. But in order to ensure capacity, the pace of production must be fast and stable. With the birth of the problem, new products, new technology, once in the automotive design phase and production management negligence, the probability of automotive product defects will be very large. What follows is the decrease of customer satisfaction and the improvement of manufacturing rework rate. In this way, there is a negative impact on both manufacturing costs and market position. Therefore, how to improve the qualified rate of automobile production is very important. The main work of this paper is as follows: first, the quality management of automobile manufacturing is studied. Two management tools, quality function expansion method (QFD) and fault mode and impact analysis method (FMEA), are studied in this paper. Second, to start their own comprehensive research, at first in the study of QFD, the introduction of questionnaire, expert interviews, card storms, KANO model and other ways to help analyze customer needs, after the QFD output quality function, This paper introduces the analysis method of double fields for FMEA, and forms two management tools: QFD and FMEA, questionnaire survey, expert interview, card storm, etc. An integrated quality management model based on customer-driven is presented in this paper, which is based on KANO model and double lattice field. Third, start to solve the problems in automobile manufacturing. New processes are used in the manufacture of Model-M, and the renewal of these processes leads to extremely high defect rates. In this paper, taking the Model-M automobile manufacturing of a certain automobile manufacturing enterprise as a practical case, the design link of manufacturing is deeply analyzed through a large number of product defect data in the first batch of manufacturing. Finally, the improved application of the integrated quality management model in the second batch manufacturing of Model-M vehicle is carried out, and the improvement effect is obtained, which verifies the effectiveness of the integrated method in helping to improve the quality. Thus, the quality management level of the enterprise is improved.
